I v t pressure. A bag made 0t this material Ill permit all the air to seep through the bag and still prevent any of the dust from escaping into the atmosphere.

Cotton felt material, however, does not 1 have sufiicient tensile strength to absorb all the strains and stresses which are normally applied to a bag, so means have been provided to properly support the bag and absorb these stresses and strainswhich occur during normal operation of a suction cleaner.

The object of the invention is to provide new and novel means to support a dust bag and to absorb the strains and. stresses which are commonly required of suction cleaner bags.

Another object of the invention is to provide a supporting sling or cradle which will support the bag and absorb the usual stresses and strains which the conventional bag must usually absorb.

Another object of the invention s to provide means which is connected to the discharge neck or outlet of the suction cleaner and also to the suction cleaner handle for supporting a dust ba Another object of the invention is to pro-- vide a sling or cradle which is made from tape or a similar material and which is connected at two points to a suction cleaner to support the bag at its underside and which will absorb the stresses and strains which are usually applied to the conventional dust'bag.

A further object is to provide a bag provided with means which will prevent the bottom or throat of the bag from coming in contact with the surface to be cleaned when the suction cleaner is being used under low places or articles of furniture, and whlch will reduce chatting.

The invention comprises in general a sling made of ordinary canvas or other similar material which is attached to the lower end of the discharge outlet of the suction cleaner, and which has its upper end secured to the suction cleaner handle. The bag is tied or otherwise secured to the sling or supporting member so that the bag is always maintained in proper normal and operable position.

in the accompanying drawings which illustrate a selected embodiment of the invention the views are as follows:

Fig. l is a side elevation of a dust bag to which the invention is applied.

Fig. 2 is a bottom plan view of a dust bag showing the manner .in which the bag is connected to the sling.

Referring to the drawings, 5 designates the ordinary discharge neck or adapter of a suction cleaner with which bag clamping means 6 cooperate for maintaining the neck 7 of the dust bag 8 in proper position relative to the discharge neck. The bag is open at its upper end at 9 so that the bag may be easily emptied. T'he open end 9 of the bag is closed by means of a clip 10 as shown, and a dust bag valve 11 may be secured inthe lower end or neck of the bag to prevent the accumulated dust gathered in the bag from falling back into the operating mechanism of the cleaner.

The sling 12 is preferably made from ordinary canvas and is secured to the discharge outlet of the suction cleaner by the clamping means 6, or in any other convenient and suitable way. The sling extends upwardly along the bottom of the bag and is suitably supported from the suction cleaner handle 13 by means of an attaching device 1%. In order to keep the bag in proper position relative to the sling the bag may be provided With strings or ties and 16 which are suitably arranged on the bottom of the bag for securing the bag to the sling. The sling provided in the present invention removes all strains and stresses from the bag as these strains and stresseswill be carried by the sling itself.

The bag is prevented from retaining other than normal operating position by means of the sling which is not onlysecured to the discharge neck and the suction cleaner handle but also to the bag at two or more points, as shown.

The invention provides means which are simple and inexpensive, and which properly support the bag in proper relative operating position with the suction cleaner handle and the suction cleaner discharge outlet.

Changes may be made in the form, construction and arrangement of the parts without departing from the spirit of the invention and sacrificing any of the advantages thereof and the right is hereby reserved to.
